Description: You are to nrite a MIPS assembly program that can multiply or divide two unsigned integers. The program will read2 unsigned integer numbers from the SPIM console and then an operation. You must support maltiplication and division You re NOT allowed to use any fom of MIPS multiplication or division instructions (such as malt, muln, div, o divu). You will implement a multiplication algorithm as described in Figure 3.3 in the testbook (i.e, vesion 3 in lecture slides) and a division algorithm as described in Figure 3.11 (e, version 3 in lecture slides) asing shifts, addition and subtraction, etc. Your program will e the SPINM sycallIO support to read a mumber from the console, then read another aumber, and finally the operator (as a string Yoa can assume that all nmbers are entered correctly, so you don't eed to do ary error checking on the mumbers. You sbould print out an eror message if the operation specified by the user is not one of the two listed below. If the operation entered is ",you should print out the product of the 2 numbers; if the operation entered is , you should print out the quouentd the lemainder. You do not need to check overiow. Assume all imputs results are unsigmed 32 bit integers. You should detect and prevent divisson by zero Hints For mulsiply, the final product will be in the lower half of the 64-bit Product register; the upper half is ofen used for overflow checking. The Product register is a pair of 32-bit registers, say(3 s4), when shifting it right one bit, Ss3'sLSB sbould become MSB of S84. The code help you with that. #dothe shifting of the product register li St0, 0x00000001 and $t0, St0, Ss3 sri Ss3. Ss3, 1 add $s4, StO, $84 Use system call mumber to read a string.
